“Two days after injecting graphene oxide into a specific region of the mouse’s brain, it behaved like other mice that had never experienced the smell of a cat in their home environment. In other words, graphene oxide inhibited the mouse’s anxiety-related behaviour,” Ballerini explains. She says that two days is roughly the time for memories to form and be consolidated in the mouse’s brain, which corresponds to the time for the symptoms of anxiety to subside.

So it removes the Flight from the fight or flight instinct. I wonder if those mice have a tendency to get aggressive or are just docile after the graphene oxide.
